CLOSURE ARRANGEMENT FOR CONTAINERS.

Application filed November 16, 1922. Serial-No. (301,297.

To all whom it may concern:

Be it known that I, VERNON L. ELWELL, a citizen of the United States, residing at Leeton, in the county of Johnson and State of- Missouri, have invented certain new and useful Improvements in a Closure Arrangement for Containers, of which the following is a specification.

This invention relates to improvements in closure arrangements for receptacles.

The primary object of this invention is the provision of an improved closure arrangement for receptacles ordinarily adapted for containing liquids, whereby a leak proof con- .nection intermediate the closure arrange ment and receptacle may be established in facile manner.

A further object of this invention is the provision of an improved receptacle for receiving liquid, such as cream, milk, and the a like, embodying a novel type of closure memher, and an improved construction to permit quick assemblage and detachment of the closure member on the receptacle to provide an absolutely leak proof joint which-cannot be come accidentally detached.

Other objects and advantages of this invention will be apparent during the course of the following detailed description.

In the accompanying drawing, forming a part of this specification, and wherein similar reference characters designate corresponding parts throughout the several views. {Figure 1 is a side elevation of the improved receptacle, showing the various details thereof in detached relation.

Fig.2 is anenlarged fragmentary transverse cross sectional view, taken at the juncture of the closure and receptacle body portions, to illustrate the manner of connection thereof.

Fig. 3 is a transverse cross sectional view taken substantially on the line 3-3 of Figure 1. n

Fig. 4 is a top plan view of the improved receptacle.

Fig. 5 is a fragmentary cross sectional view, showing the manner in whichthe' closure member or lid of the improved device is assembled to the body portion of a recep-- tacle used in conjunction therewith.

In the drawing, wherein for the purpose "#of illustration is shown but the preferred embodiment of this invention, the letter A- generally designates the improved container which may include the receptacle or body portion B, and closure lid 0.

Referring to the receptacle B, the same is preferably of cylindrical formation, and may be of any approved material providing the'beaded lower marginal edge 10. The upper portion of the receptacle body 11 is rolled outwardly to provide the annular head or roll portion 12 defining the annular passageway 13 therein. Prior to rolling of the upper edge portion 12 of the receptacle body 11, the same is slotted inwardly, so that when the roll or bead 12 is complete certain transverse passageways 14 are provided, extending therethrough, which communicate with the annular passageway 13 provided within said roll 12. A wire ring 15 or analogous loop shaped member is preferably rolled in the passageway 13 of the bead 12; the same being crimped outwardly at predetermined distances, to provide-lugs 15, which when the wire ring or loop 15 is within the bead passageway 13 extends transversely through the openings 14 in the roll or head 12, and project exteriorly of the outer periphery or circumferential surface of the bead 12, substantially as is illustrated in the various figures of the drawing. These projecting portions of the lugs 15 are adapted for cooper-- ation with the closure member or lid C in a manner which will be subsequently set forth. In order to prevent any liability of displacement of the lugs 15, and to provide a sanitary construction, the slots or openings 14 in the head or roll 12, after formation are soldered or otherwise sealed about the extendin' lugs 15. I

eferring to the closure member C, the same is preferably of the same material as the receptacle B, and may be stamped of a single piece of material to-provide the top 20 which has the annular upstanding and upwardly diverging flange 21. marginally out struck portions 30 at spaced intervals, which provide vertical relatively wide passageways 31 extending upwardly from the extreme lower marginal edge 32 of the closure roll or bead 27, and terminating in the upwardly inclining passageways 33 which offset at a greater angle than 90 with respect to the run of the vertical passageways 31.

In assemblage of the closure member 0 upon the improved receptacle B, the same is disposed over the upper bead or roll 12 of the receptacle B, so that the vertical passageway 31 of each of the outstruck portions 30 receive the lugs or outstanding portions 15 therein. When the closure member (1 has been pushed so that the arcuate top edge 35 of the roll 12 just engages the under surface 36 of the resilient packing 25, the operator by an angular movement relatively rotates the closure member C upon the receptacle B, so that the lug portions 15 ride upwardly in the inclining passageways 33 of their respective outstruck portions 30.

p This operation will have the effect of more firmly wedging the resilient packing ring 25 into engagement with the beaded top 12 of the receptacle B to provide an absolutely leak proof connection. Of course, the outstruck portions 30, the grooves provided therein, and the various lugs 15 cooperate as bayonet-joints to effectively retain the lid or closure member Cupon the receptacle B against liability of accidental detachment.

The provision of the lugs 15, inthe manner above described provide a relatively simple, extremely durable, and economical construction, being a particularly desirable arrangement in view of the fact \that the lugs 15 necessarily are subject to a shearing action as they ride upwardly in theinclined ways 33, so that the resilient packing ring 25 is placed under considerable compression.

The lugs ordinarily cast upon articles inproviding bayonet jointarrangements are not durable. The improved means of securing the leak proof connection involving the resilient packing ring 25 cooperating in its V-shaped annular groove and resting upon the arcuate upper edge 35 of the head or receptacle roll 12, provides a construction which is durable, simple, and easy of access for cleansing'purposes. In view of the provision of the bead 12 upon the receptacle B it is obvious that there need be no undue frictional engagement of contacting surfaces of the receptacle and its cover, and the attaching and leak proof connection is formed principally by the bayonet joints and the packing ring engaging the bead 12.

Various changes in the shape, size, and arrangement of parts may be made to the form of invention herein shown and described, without departing from the spirit of this invention or the scope of the claims.

I claim;

1. As an article of manufacture a container comprising a body receptacle having the upper edge thereof outwardly rolled to provide an annular passageway therein, said rolled edge being transversely apertured, a wire within said passageway crimped intermediate its ends to provide lugs laterally extending through the apertures of said roll, a lid for said receptaclebody providing an annular V-shaped recess upwardly therein adapted to receive the roll of said receptacle, said lid providing an outer depending annular flange having outstruck portions thereon providing bayonet slots adapted to receive the laterally extending lugs on the roll of said body receptacle, and a resilient packing within the V-shaped recess adapted to be clamped upon the roll of said receptacle when the lid is placed on said receptacle with the lugs fitting in the bayonet slots thereof.

2. A container comprising a body open at its upper end, a hoop'positioned about the upper end portion of said body and having lugs extendin in spaced relation to each other about t e hoop, the body being slotted and roller outwardly and downwardly about the hoop with the lugs extend ing outwardly through the slots, a 'cover having a central portion for fitting into said body and provided with an upstand ing annular flange extending above the body, an annular wall extending downwardly from said flange and having bayonet grooves leading upwardly from its lower edge for receiving said lugs, the space between the upper portions of the flange and wall forming a packing receiving seat, and packing in the seat providing a tight joint when the cover is put in place.
